A new formulation allows for doing more work inside HOSL.

Γ ⊨ e ≤log≤ e' : τ <=>
∀ Δ vvs ρ,
  spec_ctx ρ -∗
  □ ⟦ Γ ⟧* Δ vvs -∗
  ⟦ τ ⟧ₑ Δ (e.[env_subst (vvs.*1)], e'.[env_subst (vvs.*2)])

The case of lam and case expressions that before required the terms to be
well-typed now require terms to be closed.

Separated definition context and context refinement from soundness_binary file.

This is to avoid confusion when Coq loads the module.

There is one admit that needs to be taken care of. The admitted case is validity
of a monoid element of iprod. At the moment iris doesn't seem to have necessary
lemmas to prove this easily.

We still need to prove the many admitted lemmas in rules_binary module.

iris is now used as a library now.
